GPS and Sharing Waypoints Overview
When you select a new GPS source, the position, menu settings, view rotation,
and digital readouts will automatically update on the control head. To view
waypoint data on the network, it is important to understand the GPS source
and how to share waypoint data.
• Menu Settings: If the GPS source is shared, the control heads will
synchronize menu settings (Shared), while other menu settings will
continue to operate individually (Local) on each control head. When
you change a shared menu setting on one control head, it will be
updated on the other control heads that are sharing the GPS source.
• Views: The view rotation will update to correspond with the GPS
receiver. If a networked control head is not a chartplotter, it will display
chart information in trackplotter format (if it is trackplotter-capable).
• Navigation: Waypoint data can be shared, and you can build a route
on either control head with the shared waypoints. See Share
Waypoints for more information.
